Imagine a sensor shield that you can use with any of your Pycom multi-network modules. This is what you get with Pysense – a leg up to get you off to a great start really quickly. These little fellows fit all Pycom boards and contain a number of sensors.

This board is an evaluation platform for the SM130 RFID module. It includes an XBee header, PCB trace antenna, and has the layout to be used as a shield for an Arduino. There is a small prototyping area as well. This board can also be used as an antenna to the SM130 RFID module. Be sure to check the schematic for information on the connections.

Here's a dedicated and well-designed data logging shield. Adafruit worked hard to engineer an inexpensive but well-rounded design. Not only is it easy to assemble and customize, it also comes with great documentation and libraries.
